Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric walking assist vehicle which can be used as a walking stick for pedestrians.

[0002]

2. Description of the Related Art An old man with a bent waist or a person with a leg disorder may walk while pushing a baby carriage. This is because the baby carriage acts as a cane, and leaning against it reduces the force to support the body and makes walking easier.

[0003]

However, even a baby carriage requires extra force to push it, so it becomes rather difficult when tired or on a slope. From this point of view, it seems that the pram should be equipped with a power source,
Even if the baby carriage can be driven by itself, it has only that meaning. The present invention solves such a problem and realizes a universal electric walking assist vehicle having various functions in addition to simply replacing the baby carriage.

[0004]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention is directed to a steering wheel standing in the center of a traveling vehicle driven by a battery-powered motor, a seat in front of the steering wheel, and a rear opening / closing mechanism in the rear. The present invention provides an electric walking assist vehicle characterized by having a space in which a possible base is stretched.

[0005]

By taking the above means, if the base is raised and the space is opened, the pedestrian can approach the handle by entering the space and walk in a stable posture. Of course, at this time, driving the motor to drive the vehicle on its own helps walking. On the other hand, if the base is lowered, pedestrians can ride on it and move without walking. Furthermore, it is possible to put a person or luggage on the front seat.

1 is a sectional view of an electric walking assist vehicle according to the present invention, FIG. 2 is a front view, FIG. 3 is a rear view, FIG. 4 is a plan view, and FIG.
6 is a bottom view and FIG. 6 is a side view. This electric walking assist vehicle is a vehicle in which a vehicle body frame 10 is supported by two front wheels 12 and two rear wheels 14. It should be noted that the four-wheel type is used as a whole because it is the best in maintaining stability, and in some cases, the front wheel 12 or the rear wheel 14 may be a three-wheel type. A handle 16 stands up from almost the center of the body frame 10, and a box 18 is provided on the body frame 10 and in front of the handle 16. The box 18 is provided with a battery 20 and a speed reducer using the battery 20 as a power source. The motor 22 is housed therein.

The output shaft 24 of the motor 22 and the rear wheel 14 are housed in a chain case 26 extending outside the vehicle body frame 10, a sprocket and a chain mechanism (not shown).
, Which constitutes a traveling vehicle that travels by itself (with this, the traveling control means such as a clutch and a brake is naturally also provided). The motor 22 is equipped with a motor of 600 W or less, and the maximum speed is set to 6 Km / h or less so that this electric traveling auxiliary vehicle does not correspond to a vehicle under the Road Vehicle Transportation Law. This is because the electric assist vehicle is used for a wide range of purposes and is not subject to legal restrictions as much as possible, and it does not mean that the electric assist vehicle should not have a capacity or speed higher than this.

In addition, the front of the handle 16 and the box 1
A seat 28 on which a person or an object can be placed is provided on the upper portion of 8, and a step 30 on which a foot is placed is also provided on the lower portion of the seat 28. A space 32 for a person to enter is provided behind the handlebar 16 and inside the vehicle body frame 10. The space 32 is always closed by horizontally extending an openable / closable base 34. Thus, if the base 34 is flipped up to open the space 32, a person can enter the space 34 and grasp the handle 16 in a state of being close thereto. This is because the wheel base of the front wheels 12 and the rear wheels 14 needs to be long to a certain extent in order to make the electric walking assist vehicle stable, and then the base 34 becomes an obstacle and the handle 16 is disturbed. Because you cannot hold it.

On the other hand, if the base 34 is lowered, a person can ride on it, and it is possible to move while riding on it. In addition, this base 34
The support shaft 36 is provided horizontally at the front of the pace 34, and the support shaft 36 is attached to the body frame 10.
It is conceivable that the locking body 38 that can be locked to the vehicle body frame 10 is provided on the rear portion while being rotatable with respect to the vehicle body. As a result, if the base 34 is rotated around the support shaft 36 and its rear portion is lightly fixed to the handle 16 or the like, the space 32 will be opened.

Further, the handle 16 needs not only to be grasped by the hand but also to play a steering role. Therefore, the handle 16 is rotatably supported by the handle cylinder 40, the sector arm 42 is provided at the lower end thereof, and the arm 44 provided on the front wheel 12 (which is also rotatable) is tie rod. Connect at 46. As a result, when the handle 16 is rotated, the front wheels 10 are rotated and steering becomes possible. A grip 48 is provided on the upper portion of the handle 16, and the grip 48 can be adjusted in the front-back direction and the handle 1
The height 6 of the handle cylinder 40 is adjustable.

As described above, if the space 32 is opened by flipping up the base 34, a person can enter the space 32 and hold the handle 16 (strictly speaking, the grip 48). And maintain a stable posture. If you walk without driving the motor 22 in this state, it can be used as a substitute for a baby carriage or cane,
Driving the motor 22 will help walking, and will make walking easier on tires and on slopes. Also, if the base 34 is taken down and rides on it, it can be moved without walking by itself. Furthermore, if a person is put on the seat 28, it can be used instead of a wheelchair (in this case, it may be operated by oneself,
You can push it to another person), and you can use it as a carrier instead of a carrier. In addition, the seat 28 also serves as a stool for taking a rest when tired while walking while pushing the seat 28.

[0012]

As described above, since the present invention is as described above, it is a convenient universal electric walking which can be used for various purposes such as assisting walking, moving without walking, wheelchair, carrier, and resting stool. The auxiliary vehicle could be provided at a low cost with a simple structure.
